AFLAC is a flexible supplemental medical insurance where a set amount of pre-tax money is deducted from each paycheck and deposited into account. It can be used for expenses not covered by your regular medical insurance plan - such as eyeglaasses, prescriptions, daycare, plan deductibles, etc. The "spokesperson" in the AFLAC ads is a duck and comedian Gilbert Gottfried does the voiceover. All the damn duck ever says is AFLAC
